for you guys wanting OBD tuned this, it is possible! ECUtuninggroup has done it. 1995$ for the tune +1000$ deposit for their tool and laptop if you can't show up.

I don't see those specification on their website...

Alpina speed limiter is available and can be coded, but I think they have to crack encryption first. At least reset the 10 hour timelock in the DME. Then Alpina speed limiter can be set via esys.

If the DME has been in the car for more than 10 hours of driving, the timelock will prohibit coding the Alpina speedlimiter, same as it prevents coding from a 523i to a 530i spec on the N53B30. Tuners have now cracked the 10 hour timelock and are able to code a 523i to 530i spec via esys and also add the Alpina speedlimiter. The previous option was to buy a brand new DME and code that...

Oh sorry my bad!
Eurocharged did it!

That was my concern initially as I only have 3500 miles on my car, but I got some help and the difference and performance gains have been amazing.

You can tell comparing the two graphs the boost curves are very different. Our tune has boost coming a lot softer vs yours that has boost all in right away. It appears as your car is running more boost too overall. Yours being on race and ours being on pump gas would also align with that idea.

Yeah very different graphs and is it me or does your car seem to die up top after 6k?
Here are some more runs from my car. The ones revving out to 7k rpms were tune only in 4th gear which is reads lower as you know. Still seems like my power doesn't die off at 6k. But I'm not Martin Musial so educate me

AMS graph is 4th gear pull

Turned the car off, left the trunk and hood open, left the car to go to "sleep" left the car for about 1 hour
Opened hood, removed engine cover, removed ECUs, removed ECUs from "coolant" pipes with pliers
Wrote on drivers and passenger ECUs
Disconnected battery
Shipped to Belgium Monday
Received Friday
Re installed ECUs (not sure about coolant process)
Reattached battery.

Hi. Would you be able to drive down to hunnington beach or close by to meet with green turbo for a test ride in your car. He would be able to give us an unbiased viewpoint. Thanks.

Sure, maybe we meet up half way? Would be happy to.

Thanks. I informed him.

Who cares that is the risk people take. Try tuning on e-85 offer it to the customer charge more. Kinda idiotic for you to disregard this considering a ton of people would absolutely purchase an e-85 map. Simply put a disclaimed saying upgraded hpfp is recommended, wow that was so difficult right?

Who will get the bad reputation when, or if, things go bad? Details such as upgraded hpfp recommended drowns in the threads posted on the interweb after a (insert tuner name) car running E85 breaks down... If I where them I would stay out of it when they feel the way they do about it.

Why wouldn't they use 5th which is closest to 1:1 ratio. Without topspeed limiter it's the best bet. My runs were cut off cause of that.

Nice - just read the entire thread. The slower onset of torque is probably better as having all 600ft-lbs at 3K RPM as I have now makes the car misbehave (and risk detonation).

The turbos are definitely maxing out - the factory DME appears to pull back boost at higher RPMs. Maybe 700whp+ is possible with the upgrades turbos and the supporting tune.

Question I can think of:

1. Is this 91-octane compatible (for us CA daily drivers). I run 2.5psi JB4 now and no issues (over 600whp and 600ft-lbs torque)
2. Can maps be switched on the fly for 91, 95 and maybe 100 octane? Say M2 button :-)
3. OR - can a 93-octane tune be used and the car just adapts down or up based on fuel type?
4. With upgraded turbos, is running the cats (AMS hi-flow cats) compatible?
5. Any warranty?
6. Does running the tune negate the power characteristics of the CP model and makes all F10 M5's equal power-wise?
7. At what point does the stock fuel system max out? Can the car actually make 700-750whp on the factory plumbing/pump etc?

Definitely interested in the Alpha-9 package!

Can only answer to point 6. This will be a similar remap to AMS's solution in all likelihood.

Your links indicate that the realized power gains are the same post-tune irrespective of CP or regular.

That's right..even the 30 Jahre 600hp model gets upgraded to the same power gain.

I just checked the graphs you linked to, I only see one with RPM rev out to 6200 rpm, I don't see one to 7000 rpm, maybe I'm missing a link?

Looking at your dyno graphs that are plotted vs. speed these are all done in 5th gear it looks like, hitting the Speed limiter just under 155mph on all the runs (which is 6200rpm in 5th). Our dyno graph in 5th gear cut off at 6200rpm does not drop off either

I just did some more runs on the M5 and tweaked the tune a bit. Brought in a little more boost down low (more torque) and tried to run more boost up top, and it just won't. i can log requested boost by the ECU and see that at around 5500 rpm the actual boost can't maintain what the ECU is requesting. The turbochargers are maxed out at this point.

We made some more power in 4th gear with the newest tune I did, and I ran the car in 5th gear because the car will make more power under more load, which it did. Anyways I'm still tweaking it and finally back on the ECU (I haven't had time since i was tuning a few cars for a race this weekend, about 3800hp combined between 2 cars!). Will keep you all posted on the results.
